Title: Bag filter for pollution control - has venturis in bags supplied with reverse flow of high pressure clean gas for cleaning bags
Inventor: RICHARD KENNETH L
IPC: B01D46/00
Filed: 1980-08-30
Abstract: Bag filter for sepg. particulates from a gas, e.g. air, has a lower compartment for receiving gas to be cleaned and an upper compartment for discharging clean gas, sepd. by a partition contg. venturis communicating between the two compartments. Porous filter bags are vertically supported in the upper compartment with the lower open end of each bag closed around the top of the venturis. Jet nozzles are directed downwardly in each of the venturis and groups of the nozzles are selectively supplied with bursts of high pressure gas to induce a high velocity reverse flow of clean gas from the upper compartment through the bags into the lower compartment. This induces removal of particulates from the -interior surfaces of the bags into the lower compartment. Fixed vanes in the lower compartment below the inlet direct particulates cleaned from the bags away from the venturis to a discharge outlet. Groups of bags can be cleaned in turn while the other bags remain on stream. The vanes in the lower compartment prevent re-entrainment of removed particulates into those bags which remain on stream.

Title: Method for increasing the sensitivity of luminescence assays using enzymatic cyclic reactions
Inventor: KOLEHMAINEN SEPPO
IPC: C12Q1/48
Filed: 1981-02-23
Abstract: Bioluminescence and chemiluminescence assays coupled to enzymatic cyclic systems improve to a large degree the versatility of use and sensitivity of substrate and enzyme assays which are based on the enzymatic cycle principle. Besides the normal pyridine nucleotide cyclic system, it is possible to use the adenine nucleotide system if the substrates which are formed are measured using the bioluminescence assay for ATP. It is possible by using the bioluminescence assay for NADH, NADPH and ATP, and the chemiluminescence assay for H2O2 or O2<+>, to measure (to determine) many more of the substrates formed in enzymatic cyclic systems than was hitherto possible by spectrophotometry or fluorometry. The sensitivity of the measurement with the luminescence assay systems is 2 to 3 orders of magnitude greater than in fluorometry.

Title: Sealing element of special concrete and method of producing it and using it to open and close groundwater passages
Inventor: ESTERS KLAUS DIPL ING
IPC: E02D5/18
Filed: 1981-02-23
Abstract: The invention relates to a sealing element and a method of producing it and using it for sealing walls of sealing structures, preferably bored piling or diaphragm walls, for forming specific groundwater passages, with a hydromechanical cutting device having a nozzle tube preferably designed as a drill-pipe string, the sealing elements (1) being made of special concrete (1a) which consists of a supporting-grain structure (21) of gravel in the grain size of about 7 to 32 mm, the pores of which are homogeneously filled with a sealing mortar (22) of cement and insulating materials. There are guide tubes (18) in the sealing elements (1). A series of nozzles (6) can be inserted into the guide tubes (18). At least one jet nozzle (7) suitable for high pressures and high discharge velocity of the flushing medium (8) is interchangeably fastened to the lower end of the series of nozzles (6). By means of its nozzle jet (9), the jet nozzle (7) washes the sealing mortar (22) out of the special concrete (1a) and conveys it away together with the flushing medium (8) in a controllable manner through the guide tubes (18) to the surface, the supporting-grain structure (21), flushed free, of the special concrete (1a) remaining behind as a rock filter. Here, the jet nozzle (7) acts with its nozzle jet (9) across the outer surface of the sealing element (1) into the adjacent soil and at this location, through grain transposition, connects the in-place, groundwater-bearing soil (4) to the supporting-grain structure (21) acting as a rock filter. When required, the groundwater passage thus created can be partly or completely closed at any freely selected moment at a reduced pressure of the flushing medium (8) by means of the hydromechanical cutting device by the addition to the flushing medium (8) of injection substances setting underwater. <IMAGE>

Title: Plastic packaging, consisting of a container and a lid
Inventor: CHRISTENSEN SVEND ERIK
IPC: B65D41/28
Filed: 1981-03-16
Abstract: The packaging consists of a container with a lid (3) having three peripheral or one outer, one upper and one inner, sealing faces (6, 8, 16) which are separated from one another by hollow spaces (11, 17), the hollow space (17) lying nearest to the interior of the container having a shape which interrupts the capillarity, produced by a special brine content, while the second, outer hollow space (11) is shaped to receive salt separated by osmosis. The inner, smooth container wall (1) merges at the top through the upper sealing face (8) into a flange section (4) which is shaped like a truncated cone, extends downwards and continues at the bottom in a cylindrical flange section (5) which engages with the cylindrical inner face of the lid part (10) and is engaged at the bottom by the bead (12). The lid face (19) is countersunk by means of the wall part (15) whose thickness increases gradually towards the bottom and which has a greater diameter than the container ahead of the sealing face (16). Apart from the sealing engagement on the sealing face (16), it is achieved that the wall (3) and thus the flange section (5) is pressed against the lid part (10) for the purpose of sealing on the sealing face (6). For the purpose of lid stacking, the lid part (10) is connected to a cylindrical foot piece (14) by means of a sloping, outwardly extending part (13), and the wall part (15) is connected to the lid face (19) by means of a sloping, inwardly extending wall part. Firstly the shaping of the lid and of the container prevents salt of a brine content being deposited on the outside of the packaging and secondly it is achieved that the lid and the container can be stacked separately for storage, and that the container can likewise be stacked with the lid fitted on, in that the shape of the lid additionally ensures that it is directed precisely onto the container mouth (2) when it is fitted on. <IMAGE>

IPC: E05B63/04
Filed: 1981-03-21
Abstract: Inserted into a furniture lock is a cylinder lock, of which the rotary position relative to the furniture-lock can be varied. The cylinder lock can be fixed in the individual rotary positions which correspond to the possible installation positions of the furniture lock. For this purpose, the cylinder-lock case has at the edge, in the region of the blocking nose, a plate which differs in its contour from the circular shape, is located at least partially within the contour of the cylinder-lock case and is preferably symmetrical relative to at least one axis and to which is joined an annular groove, the inside diameter of which corresponds approximately to an incircle of the cut-out of the furniture-lock cover. The plate can be inserted through the cut-out of the furniture-lock cover and, with the annular groove lying in the plane of the furniture-lock cover, the cylinder lock can be rotated and, as a result of rotation, detained against being pulled out. The detention is achieved by means of a spring-loaded locking pin which is axially displaceable in the cylinder-lock case and opposite which bores or radial slots for rotation prevention are arranged in the furniture-lock cover.

Title: Method for launching munitions from a combat aircraft
Inventor: BAUER MICHAEL ING GRAD
IPC: F41G3/24
Filed: 1981-07-15
Abstract: A method for launching munitions from a combat aircraft is proposed. The combat aircraft has a weapon computer which determines the distance of flight and the direction of the flight path (trajectory). The weapon computer defines the values of the distance of flight and the flight direction and, in addition to this, the elevation and azimuth viewing angles to the expected impact point (5) on the ground are determined. A release sensor (2) for launching the munition is controlled from the abovementioned values such that it is always looking at the impact point (5) during flight. The expected impact point (predicted impact point) (5) is superimposed on a target object and the launch of the munition is initiated purely by the sensors when they coincide. <IMAGE>

Title: Device for monitoring the all-clear or occupied state of a rail section
Inventor: UEBEL HELMUT DIPL ING
IPC: B61L1/16
Filed: 1982-01-18
Abstract: The subject of the invention is a device for monitoring the all-clear or occupied state of a rail section with axle sensors which are arranged offset with respect to one another in pairs at the start and at the end of the rail section and form a counting point. The axle counting pulses emitted by the axle sensors are fed to an evaluation circuit and evaluated there as to their number and sequence. In contrast with known axle counters which detect the all-clear state of the rail section by comparing the number of axles which have entered the section with the number of axles which have left it and which are prone to counting errors, in the device according to the invention the axle patterns of the incoming and outgoing vehicles or vehicle combinations are recorded and compared additionally or exclusively. For this purpose, the axle patterns are entered with a timing scale or a length scale into the axle pattern memory (SP1, SP2) assigned to the counting points and compared in a special comparison device (VG). As a result of the large degree of redundancy of an axle pattern, a reliable track all-clear report is possible even in the event of individual counting errors occurring. <IMAGE>
